how to remove 1KZ intercooler and clean throttle body

Ok well I'm wondering should I do this to my petrol Prado? Don't laugh!! I'm useless at this stuff and would rather do what I can and save money rather than my mechanic ripping me another one

well finally got round to cleaning mine this eve...it was a mess, thick black gunk all over the shop...changed the plugs whilst i was at it. It was a super easy job. It never ceases to amaze me how easy the prados are to work on. Most cars to do anything more than an oil change you need 3 pairs of hands and a tentacle but the prado comes apart and goes back together so easy!
Anyway took it for a test run up mt cootha and she really pulls now...

only one issue...engine light came on as soon as i started it which probably means i got a bit happy with the carb cleaner...this happen to anyone else? There was no missing/smoke etc and the car runs perfect..actually better than ever! Im thinking maybe its the sensor in the intercooler? Not the turbo pressure one but the other one? Anybody care to shed any light on this? And no i didnt block of the EGR..

Has anyone tried squirting engine conditioner down the intake of the turbo to clean the vanes of the turbo, the inside of the intercooler, the throttle body and manifold of a 1KZ-TE, to save pulling everything apart?

Cheers,

I just pulled mine apart which was easier than I thought and gave it a clean out! My cars done 115000 so I suppose it shouldn't be to bad considering its a petrol to but still dirty all the same.

The only question i have is that is revving really high when idling and I'm not sure whether a good run will fix that or not...... If not what have I done 😱

Check this one out guys off my 2005 280,000km.

oh yeah and after cleaning throttle body, manifold and new injectors still running at 16.8 lt per 100km with 265 70 17 that is according to trip computer so not totally accurate.
Anyone got any ideas why its using so much juice??

Forgot to hook the EGR back up....D'oh

Now back to normal running

Maybe check the air intake, air filter etc? Also in the intercooler there is a sensor that i noticed gets gunked up so i gave it a clean. Maybe check that?

I've got a new filter and recently installed the snorkel, so i don't think air getting in is the problem..... do yu mean the sensor in the elbow above the throttle body?

Its in the intercooler above the throttle body yes. Have a look and see if its gunked up. Not sue if this will help but wouldnt hurt to clean it.

I dunno about you guys but i dumped half a can of carby cleaner through the intercooler as well. Maybe im going back to my old days of the '89 Skyline GTR and having the cooler full of crud from the turbo under high boost. Still, i got a lot of the usual crap out of it as well. the cleaner the intercooler internally and externally, the more efficient it should work, the better performance.
My biggest suggestion for tackling this job, DON"T HAVE A HANGOVER! ugh......

Hey guys,

Does anyone have a list of the gasket numbers you should be replacing after completing the clean on the throttle body and manifold? Also to the mechanically minded, should the oil and filter be changed immediately after this is completed? or after driving a few kms?

Thanks

Troy

I am sure you are already doing this, but just for your information. You should replace your gaskets. Toyota part numbers. Intake manifold to head gaskets 4 x 17177-67011. Torque from the centre of the manifold out to the ends 29Nm. Throttle body (Venturi) gasket 26171-67030. Torque the four bolts to 20Nm. The throttle body needs to be cleaned from time to time, check them every 50,000 kms or so. I always use Locktite Carb. cleaner for cleaning the throttle bodies, also good for cleaning the manifold. Any good quality carb. cleaner will do. Be careful not to drop the throttle body as it could damage the motor. I always remove them from the manifold because of dirt etc..You will get better performance and economy with a clean throttle body. Glow plugs should be changed every 100,000 kms with the injectors. For glow plugs I always use JKT CP-22, they are made in Japan. Set of 4, $110.00 trade and go exchange on the injectors.
Hope this helps.

Cheers,
Scott.
